NIOSH considers all Cr(VI) compounds to be occupational carcinogens. The purpose of this webpage is to provide information regarding Cr(VI). 17034 Classification. Where Does Hexavalent Chromium Come From? Hexavalent chromium is also present in fumes generated from welding stainless steel, chromium alloys, and welding rods. Hexavalent chromium is harmful to the eyes, skin, and respiratory system. Hexavalent chromium deposition was highest in the alveolar region (14%) compared to other regions of the respiratory system. Using a respirator on the welder to filter out the “smoke” particles is the last line of defense. Respiratory tract (Inhalation damage to mucous membranes), perforation of septum (tissue between the nostrils of nose), lungs, eyes, skin, liver and kidneys are some examples. If your employer’s hexavalent chromium exposure assessment shows you could be overexposed, you’ll have to wear a respirator. # WC-HEX-10X-1. 100 mL. Hexavalent chromium is a toxic form of the element chromium, found mainly in products of industrial processes such as metal finishing, wood preservatives, fungicides, pigments in dyes, paints, and plastics. Cr(VI) is one of the chemical states of the element chromium (Cr). Consequently, when working to comply with the provisions of the OSHA Chromium VI standard (29 CFR 19101.1026) one would be well-advised to review the Material Safety Data Sheets (MSDSs) for the welding consumables to determine if chromium (that may be converted to hexavalent chromium during welding) is present in the consumables. The body can detoxify some amount of chromium (VI) to chromium (III). Chromium is the 21st most abundant element, the sixth most abundant of the transi- tion metals, and is mined as the principal ore chromite (chrome iron ore), FeCr2O4. Engineering Controls: Not normally needed. Hexavalent chromium [Cr(VI)] is one of the valence states (+6) of the element chromium. Hexavalent Chromium, typically generated by industrial processes like welding and thermal spray. Cr(VI) is considerably more toxic than Cr(III). Hexavalent chromium (Cr(VI)) compounds are recognized as carcinogens in the respiratory tract, giving rise to cancers of the lung, nose and nasal sinuses, especially in certain occupational environments.

Chromium metal is added to alloy steel to increase hardenability and corrosion resistance. So the maximum concentration of hexavalent chromium a welder could safely work in with this respirator is 10 x 5 = 50 µg/m3. This OSHA Standard requires initial worker sampling in any activity that could contain Chromium and thus potentially overexpose that person to Hexavalent Chromium. Chromium III is much less toxic than chromium (VI). Hexavalent chromium (Cr(VI)) compounds are a large group of chemicals with varying properties, uses, and workplace exposures. Humans can be exposed to chromium via inhalation, ingestion or skin contact. A brief overview of the standard can be found in our document Highlights of the New Hexavalent Chromium Standard. However, like most personal protective equipment, respiratory respirators have limitations with their usage and effectiveness. It is also known as hexavalent chromium, and used as an anti-corrosive agent in paint and coatings. A worker exposed to hexavalent chromium may experience symptoms such as sinus irritation, nosebleeds, ulcers (stomach and nose), skin rash, chest tightness, wheezing and shortness of breath. Future research should focus on other welding processes such as SMAW, FCAW, and gas tungsten arc welding. Hexavalent Chromium is the most toxic form of chromium. Hexavalent chromium may exist in aquatic media as water soluble complex anions and may persist in water (Callahan et al., 1979). Exposure to hexavalent chromium [Cr(VI)] through the inhalation route is associated with increased lung cancer risk among workers in several industries, particularly in chromate production workers exposed to high concentrations of Cr(VI) (≥ 100 μg/m(3)) in which clear exposure–response relationships and respiratory irritation and tissue damage have been reported.
